Hello,
I am working on a project which plans to run phenotyping algorithms expressed in CQL against an OMOP repository. Located a CQL to Expression Logical Model (ELM) translator so the query is now in computer format. The next step is to convert the ELM representation to OMOP JSON and use the WebAPI to run the query.

Are there projects completed or in process which attempt a similar
process?

Is there a JSON schema available to better understand how to conduct
the ELM transform?
